Following our introductory blog post in which we explored mesh shaders and the Next Generation Geometry pipeline, we will cover some best practices for writing mesh- and amplification shaders. In the second part of this post, we will also look at how the AMD Radeon™ Developer tools can be used to profile and optimize mesh shaders.
